Abstract

L'invention concerne un procédé pour produire un nombre aléatoire selon des principes de mécanique quantique, et un générateur aléatoire servant notamment à mettre en oeuvre ledit procédé. L'invention est fondée sur la sélection de trajet fondamentalement aléatoire d'une particule quantique sur un séparateur de faisceaux (8, 18). Des détecteurs (D1, D1', D2, D2') servant à détecter les particules sont associés aux sorties (11, 12, 16, 17) du séparateur de faisceaux (8, 18). Ces détecteurs ou leurs événements de comptage représentent différentes valeurs numériques de la séquence aléatoire. La production d'un état à particules multiples dans le canal de sortie (11, 12, 16, 17) du séparateur de faisceaux (8, 18) ainsi que plusieurs particules arrivant sur le détecteur (D1, D1', D2, D2') permettent d'améliorer considérablement de manière avantageuse la probabilité de réaction du détecteur et par conséquent la probabilité d'obtenir un événement de comptage valorisable pour chaque état à particules multiples produit par la source (3, 3'). Il est ainsi possible d'obtenir la séquence aléatoire plus rapidement et de manière plus fiable qu'avec une détection de particules uniques.
